Approximately 25,000 people attended the 2025 ETHDenver conference in Colorado, held from February 23rd to March 2nd. The event featured Colorado's governor, representatives from numerous crypto companies, and U.S. lawmakers.

Launched in 2017, the annual Ethereum-focused conference began this year with its traditional BUIDLWeek, a gathering of developers for technical presentations, workshops, networking, and social events. While some attendees noted concerns about declining major token prices, the overall atmosphere remained optimistic.

Families attended in large numbers, with children entertained by various mascots, including the iconic ETHDenver Bufficorn – a buffalo-unicorn hybrid. Adults enjoyed activities such as poker games, Dogecoin (DOGE)-branded vehicle giveaways, and spork-themed merchandise (SporkDAO manages the event).

Colorado Governor Jared Polis addressed the opening ceremony on February 27th, jokingly attributing Denver's unusually warm weather (above 60°F/16°C) to his efforts. While many panels covered diverse industry issues, from combating North Korean hackers to the role of crypto in banking, a dedicated stage on February 28th focused exclusively on policy matters.

Policymakers, including Governor Polis, have enabled Colorado residents to pay taxes using cryptocurrency since 2022. Colorado is also one of the few jurisdictions allowing residents to use digital identification cards on their phones in certain situations. These factors likely contributed to ETHDenver founder John Paller's statement that the conference has no plans to relocate.

"We are centrally located, easily accessible, fun, and a hub of innovation," Governor Polis stated at ETHDenver, referring to Colorado.

In the wake of SEC case dismissals

Hester Peirce of the U.S. Securities and Exchange Commission (SEC) spoke at ETHDenver in 2024. Although she did not attend this year, the SEC's actions significantly impacted the event following their February 27th announcement dismissing an enforcement action against Consensys.

"Like many others in the community, we've recently been relieved of constraints," said Consensys CEO Joe Lubin during a February 27th panel. "The attacks from the former SEC are behind us, and we are eager to resume our strong advocacy for Ethereum, Metropolitan Ethereum, and the industry as a whole."

Bo Hines, executive director of President Donald Trump's crypto working group, cancelled his scheduled ETHDenver appearance. Hines will be hosting a crypto summit at the White House on March 7th, expected to draw numerous digital asset CEOs and leaders.
